Patent DE-3614311-A1 (DE)
Title: Propulsion system for aircraft
Inventor: KASTENS KARL DIPL ING
IPC: F02K3/12
Filed: 1986-04-28
Abstract: This propulsion system for aircraft comprises gas turbine jet engines, which in accordance with Fig. 1 have two separate combustion devices (11) and (12) and three flow circuits for generating thrust, which circuits obtain their flow energy from a crossflow fan (17) connected on the inlet side, the rollers (13) and (18) of which are driven by a turbofan (14), which is acted upon by the gas jets both of the main flow circuit (8) and of the by-pass flow circuit (9). An axial displacement of the rollers deprives the main flow circuit of energy and results in connection of the radial flow circuit (10), which is located in a swivelling flow housing (19), mounted perpendicular to the engine longitudinal axis and serves for generating the radial or vertical thrust. In this switching process, however, the horizontal thrust of the by-pass flow circuit remains undiminished. Furthermore, this propulsion system has no air inlet apertures pointing in the direction of flight, since the intake mouth (5) of the air inlet section (6) is directed towards the tail and draws the operating air for the crossflow fan from the mixing flow of the thrust jet. <IMAGE>

Patent DE-3629447-A1 (DE)
Title: Method and device for oxymetry
Inventor: BAHR DENNIS E
IPC: G01J1/16
Filed: 1986-08-29
Abstract: The oxygen saturation of the blood of a patient is determined by guiding pulses of red and infrared radiation from radiation sources through a body part of the patient. A detector determines the intensity of the radiation which has passed through the body part, and delivers an output signal which indicates this intensity and is filtered and split into two signals, specifically into a red channel and an infrared channel, by means of sample-and-hold circuits which are synchronised with the pulses for the red and infrared light sources. The outputs of the sample-and-hold circuits pass through low-pass filters which deliver output signals which specify the intensity of the red light and infrared light radiation picked up by the detector. In addition, the red and infrared signals are led through high pass filters in order to produce signals which contain only the time-variable component in the emitted intensities. These signals are fed to a digital control circuit which determines the non-temporally varying values of the red and infrared signals, determines the peak-to-peak values of the temporally varying components of the signals and forms a ratio of the peak-to-peak amplitudes to the non-temporally varying values of the red and infrared signals. This ratio can then be used for the purpose of determining the oxygen saturation as a function of the ratio.

Title: Catheter for producing or extending connections to or between body cavities
Inventor: STRECKER ERNST PETER PROF DR M
IPC: A61F2/92
Filed: 1986-11-28
Abstract: The catheter receives an endoprosthesis which can be inserted, for example, into a vessel in the correct position together with the catheter and can be implanted in the vessel by radial dilatation and subsequent fixation in the dilated position. The endoprosthesis may surround a portion of the catheter under prestress, so that it is held essentially fixed axially. It is separated from the catheter by radial dilatation on implantation. The endoprosthesis can also be held, however, essentially fixed axially on the catheter by mechanical means who are no longer effective after the implantation due to radial dilatation or which can be removed after the implantation, so that the catheter can be withdrawn.

Title: Device for welding plastic profiles to form frames for windows or the like
Inventor: STAEUDLE ROLF
IPC: B29C65/20
Filed: 1986-12-01
Abstract: Device for welding plastic profiles to form frames for windows, doors and gates, having at least two welding units. In the case of known welding devices, rectangular frames are welded together at a mitre angle of 45@. In modern housing construction, frames with segmented arches, pointed arches, more-centred arches or circular arches are increasingly desired, which then have to be joined together with different mitre angles. Different mitre angles cannot be set with conventional devices. Work can be considerably facilitated if at least two of the welding units 4, 4' are arranged so as to be rotatable about a pivot axis 9 extending perpendicular to the frame plane for the setting of different mitre angles 5, the outer edges 11, 11', 11'' of the plastic profile frame parts 2, 2', 2'' to be joined to one another intersecting one another in the welding layer in this pivot axis 9. In particular if the mitre angle is electronically set via an EDP system, the device makes possible very efficient welding, even for frames of varying shapes and dimensions with very variable series production. <IMAGE>

Title: Device for improving the return loss or loop gain in intercom devices
Inventor: GENUIT KLAUS DR
IPC: H04B3/21
Filed: 1987-02-28
Abstract: In a device to improve the return loss or loop gain in intercom systems, in which at least one filter with a comb-filter-like structure but with pass bands and stop bands offset against one another in each case forms a chain circuit, thereby increasing the overall loop loss, it is proposed to arrange the pass bands and stop bands of the filters in a non-harmonic relationship, to implement increasing stop band attenuation with increasing frequency and furthermore to design the respective pass bands and stop bands of the bandpass filters significantly below 1/2 third octave. Finally, the spectral components which lie in a stop band can also be shifted into the nearest adjacent pass bands and added to the spectral components which have been allowed to pass through. Each telephone station preferably has two filters with different structures so that the speech paths in each case have a given, albeit different, transmission function, whereas the transmission function for the acoustic and electric return loss is virtually zero.
